To (ZZZ whom it may concern:

Be it known that I, ERNEST FRAZER, a citizen of the United States. residing at Portage Lake, in the county of Aroostook and State of Maine, have invented certain new and useful Improvements in Anvil Horseshoe Vises, of which the following is a specification.

My invention relates to vises of that class which are operated by foot power and more especially to that type of vises used by blacksmiths and which are specially designed for the forming and calking of horseshoes, and'also for the holding of metal for the purposes of making machine bolts, and sled shoe bolts.

The objects of my invention are to provide a simple, strong and quick-acting vise of this class and capable of powerful leverage and grip, and which is operated by little exertion on the part of the operator.

Another feature of my invention is to provide a certain kind of vise. This vise being formed by the jaws of the tool and each of these blocks is provided with a graduated series of semi-cylindrical recesses, arranged opposite each other in pairs, so that metals of different sizes may be gripped by these jaws and calks and bolts of difi'erent diameter may be formed.

To these ends the invention consists in certain novel features, which I will now proceed to describe and will then particularly point out in the claims.

In the drawings Figure 1 is a side elevation,

Fig. 2 is an end elevation,

Fig. 3 is a plan view of the vise.

In the same drawings, 1 denotes the stationary side of the vise rigidly connected to the stand or bottom 15. The top of this stationary member forms one of the jaws. Pivotally connected to the side 1 at 12 is'the foot-paddle 3, which operates the other jaw 2 of the vise by means of link 6 which is pivotally connected to foot-paddle 3 by pin 13 and to side 2 by pin 14. This jaw 2 is pivotally connected to 1 by pin 8. The footpaddle 3 is provided with a recess 4: so formed as shown in Fig. 3, so as to allow the operator to easily exert his entire weight on it. Spring 5 is connected to foot-paddle 3 and base 15 and in the normal position as Specification of Letters Patent. Patented June 13, 1922.

Application filed November 3, 1921.

shown in Fig. 1 exerts an upward pressure on 3 and by means of link 6 and pivot 8 forces the jaw 2 away from contact with jaw 1. At a suitable distance above pivot 12 and forming part of member 1 there extends perpendicular to member 1 an extension or stop 7 for the purpose of limiting or gauging the extent to which jaw 2 may be moved away from jaw 1.

The jaws of the tool constitute die blocks being each provided with a graduated series of semi-cylindrical recesses 10 as shown in Fig. 3, arranged opposite each other in pairs. Any desired number of these pairs of rerecesses may be employed, and they are graduated in size so as to adapt the tool to hold and form calks of any desired shape or thickness. This is of the utmost importance,

so that the same jaws may be used for difi'erent sizes of calks. t

The operation and advantage of this vise in practical use will be readily understood by those skilled in the art.

I do not wish to be understood as limiting myself strictly to the precise details of construction hereinbefore described, and shown by the accompanying drawings, as the same may he obviously modified without departin from the principle of my invention.

aving thus fully described my invention what I claim as new and desire to secure by Letters Patent is: e

1. An anvil horseshoe vise of the class described comprising a stationary vertical jaw arm being provided with an extension so as to limit the opening of the jaws.

2. An anvil horseshoe vise of the class described comprising a stationary vertical jaw arm at the top of which and at right angles thereto and forming an integral part therewith is a stationary jaw member, a movable vertical jaw arm and a jaw member integral therewith and at right angles thereto, oompl'eting the vise by parallel contact with the stationary jaw member, both jawsfiof saiclf vise being provlcled with sem1c1roular1aper;

tures of various sizes, each semicircular aperture of the stationaryjaurbeing coincident with the semicircular aperture on the novable jaw member so as to make contact with the stationary jaW me1nber, and meansto i keep the anis apartvivhenfithe machine is not in operation comprising a spring rigidly connected to-the base and to the foot treadle, andjso eonstructed'that it presses up against t ERNESTFBAZERJ 1'
